i iitb. i'efei'ence in the drawings, 1 designates the base of the machine 031 which is mounted two frame-standards 1 and 12. On the sizznderii 12 i. have moimsed a plate 13 having its from provided with two psiaiiel, iongitudiwily-disposed grooves 14: and in each 017 which grooves are momma ed two ions 15 so carry i'ne carriage 16, which carriage is supported in position against the face of the 13 by niesns oi the iiciits 17 passing through the backpiate 18. Positioned against the front face of the carriegepisse I have mounted piste is memo? a forxn piai e 3.9 which eci an and iiteysti to the ifotatabie shortshaft 20. This shaft is also mcunsed so the oarriage-plsie and in order is permisoi longii uiii mevemene of the carriage this ehsf': is prev. ed vi e reii 2-1 which rotates with the shift in the siot owned in the pieie While a sick of the diameter oi? this si'iefi is formed in the fmn1cmember A messing metion is transmitted 50 this V 24.- ihi ougiz the pinion :25, gear 26 and. i eleseojoing connec'- iiig shaft 27, she length eff which shaft ci'isnges so aecemznoete the irevei of the carriage.

The form 1'3 is always of a. shape is coniik'fli the iiie'vement oithe Work Yeieiive $0 the fluidspplying device, pieseniiy described. The WOZK in this perticuiar case 15 shown to be e shoeqlpper to which if desire to apply a narrow iine er strip of liquid cement for the purpose of fastening the foxing portion of the shoe sole hei eco and in obtaining this pa'ri'icnier iesuit l: mount a pair of pins en eiie form 19, which pins ai'e zzcispiecl'te enter corresponding holes 33 in the last or siieesuppor 34, see Fig. 5, and on this East I have mounteri e shee upper 36 to which the cemeniis so be sppiiedi I do nos"; wish be be restricted $0 the use {if any particular deuce for eppiying ibis Ci?" rotate in over ment to a shoeupper as any suitable means may be employed but for convenience I have herein shown a brush Ellwhieh is mounted on a support 38 extending outward from the guide roll 28, the bristles of the brush being on substantially the same plane as the contact surface or" the guide roll whereby by the rotation of the form 19 the surface to be treated is continuously presented to the brush.

The cement may be plied to the brush from the tank 3!) above or other suitable source, through the pipe 40, and by means of this brush a line or narrow strip of cement may he applied about the lower edge of the upper and after one or more coats have thus been. so applied the SllOQdlPPBl may be removed and the losing portion applied to this cemented surface, thus saving much time and the employment of skilled labor in performing this work.

Neither do I wish to be restricted to the use of a brush for applying this cement to the orl; as in some cases a pipe all may be employed which is led over the portion to be treated and the fluid may be sprayed or otherwise spread upon its surface.

I have shown and described my improved machine as manipulating a shoe-upper for the purpose of applying cement thereto, but wish to be restricted to the appliautomatically supl do not cation of cement to a shoe as any other lluid suc'lras garnish or shellac may be applied to any ortion of the surface thereof; neither do l. wish to be restricted to operating upon a shoe upper in this machine, as the same may be adapted for manipulating andtreating the surface of any other kind of work. T hen again I have shown the work as being rotated and the tluid-applying device as held in a relatively-fixed position, but in some instances the work may be fixed and the fluid-applying device revolved about the work.

l have also shown and. described a machine for operating upon a single piece of work, but in some cases a plurality of forms and work-supports may be employed and driven in unison, one arrangement of which construction is illustrated in Fig. 6. both of the forms shown being operated in unison throfugh a sprocket chain 42 working over the sprockets 433.

This fluid-applying machine is very simple in construction and by its use skilled labor may be dispensed with and much time saved in the application of fluids to the surfaces of work to be treated.

The foregoing description is directed solely toward the construction illustrated, but I desire it to be understood that l reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited onlyby the terms of the appended claims.

I claim:

l. An improvedmethod of spreading a fluid coating upon the surface of work, which consists in providing a non-rotatable spreader and automatically feeding the fluid to the point of application and causing a relative movement between said spreader and the work.

2. An improved method of applying a tluid coating to the surface of work, which consists in rotating the work and automatically feeding the coating material to the applying device.

3. An improved method of applying a fluid coating to work having an irregular surface. which consists in providing a fluidapplying device, rotating and guiding the work to continuously present the surface to be treated to the point of application an automatically feeding the coating material to the applying device.

4. An improved method of applying a fluid coating to work havin an irregular surface. which consists in definitely locating a fluid applying brush at a relatively fixed point. rotating and guiding this portion of the surface oi. the work to be treated, presenting this portion continuously to the brush. and automatically supplying the brush with the coating material.

In testimony whereof I allix my signature.
